在使用Maven时，如何解决在Eclipse中显示但不在Eclipse中显示项目的编译错误？

Question

I'm getting compilation errors when I open a specific class file in Eclipse. However, the class doesn't show a compilation error icon in the Project Explorer. I have enabled dependency management by right-clicking the project and using the Maven menu.

I'm using Eclipse 3.7.1 and Maven 2.2.1.

Answer 1

Use Package Explorer, not Project Explorer. It's a lot more reliable for Java projects.

Answer 2

I've not seen this problem before, but I'd try performing the obligatory clean and build all on the project. I suggest making sure the following options are checked in Preferences -> Java -> Compiler -> Building:

• Scrub output folders when cleaning projects
• Rebuild class files modified by others

There are several good suggestions in the question linked by bdill , specifically to try updating your project configuration from the pom.
